Anyone have any advice on how to set up this model in a Wilderness system Pungo. My friend bought the kayak and likes it so much that he thought he could easily install a portable fish finder, but can't get it to work right. Thought it was a transducer issue, then tried a different battery hook up (started with a 11 1/2 volt setup of 8AA batteries)then tried a small 12 volt battery setup. Manual has been read word for word trying to solve the problem when I said I'd throw it out to the fisherman on this site. Hopefully someone has some suggestions we can try before he throws it in the lake!!!! He even went out and bought a 2nd one thinking it was a faulty transducer. Any suggestions would be greatly appreciated. Thanks.
